Cost-benefit analysis was applied to estimate the economic consequences of precocious maturation among hatchery-reared Atlantic salmon (Salmo salar) sea-ranched in the Baltic Sea. Data on the rearing and release costs, fishing costs, catch benefits, catch size, catch age and survival of previously immature and mature salmon in Carlin-tagged groups released into the Gulf of Finland in 1981–2005 were used in the analysis. Previously immature and precociously mature salmon differed in their marine growth, survival, sea age at maturity and migration behaviour. Precocity reduced the net present value (NPV) of the releases due to the lower catch age and marine survival...</br>
